A 20-metre-long 'icicle' is seen on the side of a building in Changchun, capital of northeast China's Jilin Province. The icicle was formed by a leaking heater on the roof of the 7-storey building. On the ground under the icicle is a 30cm thick ice pool, which locals fear could prove dangerous for people walking past.Picture: HAP/Quirky China News / Rex Features
